Application led April 7,

T o all whom t may concern.' r

Be it known that we, SvnND M. MEYER and WILLIAM JAMES, citizens of the United States, and residents of the borough of Brooklyn, 'county of Kings, city and State of New York, have invented certain new and useful Improvements in Storage Batteries, of which the following is a specification.

The present invention relates to storage batteries, and belongs to that class which have a cylindrical container enclosing cylindrical electrodes. The invention relates particularly to details of construction, which can better be described by reference to the accompanying drawings, in which;

Figure 1 represents a vertical section of our lmproved battery;

- Figure 2 a plan;

` Figure 3 a horizontal section.

Figure 4 shows an assembly of a positive electrode; i A

Figure 5 the centralizing disc.

Figures 6 and 7 are vertical sections and horizontal plan of the core of the positive electrode with the cylindrical casing and the base cast,l integral therewith.

The cylindrical cell 1 of hard rubber or other suitable material has at its upper edge a screw-threaded rim, 2. The circular cover 3 also of hard rubber or other equivalent material has a flange. 4 screw-threaded interiorly, so as to be screwed on to the cell. A soft rubber washer in the shape of a dlsc 5 and having a diameter suilicient to cover the edges of the cell is clamped between the cover 3 and the cell 1, when the cover is screwed in place. Thru this cover and washer extend the yterminals 6 and 7 ofthe negative and positive electrodes respectively and the screw-threaded portions 8 and 9 are held ,by nuts 10 and 11. At 12 we show a protecting cap over the center 'screw and 13 is a conductor which lalso extends thru thel cover but not thru the rubber disc, and serves the Apurpose of bringing the positive electrode terminal out to one sidewhere it STORAGE BATTERY.

of an alloy but its constitution forms no part of the present invention. The positive electrode consists of a cylindrical casing for holding the active material. This casing is made up of a central casting 16 surrounded by a' cylinder 17 both of which are held between end ieces 18 at the bottom and 19 at the top. Sgrews 20 on the central core enable these end pieces to act as clamping nuts to hold the cylinder 17 and the core 16 in place. The core 16 has radiating ribs which are full vof perforations and the cylinder 17 is similarly perforated. Both cylinder and core as well as the end pieces are all adapted to be made by the die-casting process, and as shown in Figure 6 a taper is given to the casting to facilitate withdrawal from the lln the construction shown the central core has three wings 21 thus forming three' chambers 22 in which the active material is pressed. Access to the active material by the electrolyte being had thru the perforations 23 in the cylinder,

At the lower end of the positive electrode is secured by any suitable means an insu-` lated disc 24 of sulicient diameter to hold that end of the electrode from lateral displacement fitting .as it does more or less closely between the vertical walls of the cylinder. It is provided with orilices-25 thru which sediment may drop into the space 26 between the disc and the bottom of the cell. a

We claim 1. A storage battery electrode comprisin a central cast metal core with perforate radial ribs a perforated metallic cylinder surrounding the core, metallic end caps tted to the cylinder and closing same at top and bottom so as to form with the cyland cylinder, spaces A,for active material, ,a

screw threaded stud on the core with clamping nut for bindin all'the parts to ther and a second nut or supporting sai ftud. on the cover.

y east metal core. with radiating perforated ribs. a perforated metal cylinder tit-ted over said' ribs, and metallic end caps bet\veen which the cylinder and core. are clamped, the spaces between these elements being filled with active material. the electrode having a binding post protruding thru the cover and having `atthe lower end aeentralizing disc of insulatingmaterial. i

4. A battery 'having a cylindrical cell and circular cover adapted to'be screwed together and a soft water prooi` Washer interposed 15 between them and clamped by the cover to the cell so as to forni a watertight joint.

5. lA battery having acylindrical cell a cover screwedthere'on a soft insulating washer between them andelectrodes pro- 20 washer.
